IMPROVEMENT IN CORN-PLANTERS.

Specification forming part of Letters Patent No. 156,367, dated October 27, 1874; application filed y l n August 15, 1874.

TnfaZZwhom iti'nay concer'ni v A l Be it known, that I, JOSEPH A. MGCLURE, of Philadelphia, in the county -of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Gorn- Planters; and I .do hereby declare .that the following is full, clear, and exact description thereof, which will enable others skilled in the art to which it pertains tov make 'and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

his invention relates to a new and useful machine for planting corn and other seeds;

and it cosistsof seed-hoppers provided with beveled andinclined guards, and mechanism for operating a valve for dropping seed. It

In the accompanying drawing, Figure l is a' plan view of my machine. Fig. 2 is a side e1- Fig. 3 is a cross-section on linea' w of F-ig. 1. Fig. 4 is a front .view of one of the driving-wheels, with cap of hub removed. Fig. 5 is a crosssection online y y of Fig. 4."

The main frame A A is supported on two driving-wheels, B B, on the axle S, which is secured on the rear part of the frame, and at the front by an adjustable caster-wheel, C. This wheel C is connected with the front crosspiece B by an eye-clamp bolt, c, by means of which it is made adjustable to any desired height by clamping the standard c', and being secured by a nut, c", The lower end of the standard is held to frame A by brace c3. f A scraper, c4, is secured to the standard to clear the dirt fromthe wheel. To the main frame A is connected an auxiliary frame, D, adjustable by slotted standards cZ d. On this frame is secured a cross-bar, I, to the outer ends of which the hoppers F F are attached. The hoppers are provided with small rollers f j', which have cavities in their peripheries for receiving from-the hoppers the corn to .be drop ped at regular intervals.

the sides of the hopper, and protrudes at both sides thereof', being provided at one end with cranks f1 f1, the pins of which are connected by a conneeting-rod,f2, across the machine. f 0n theother end of the small shaft issecured an eccentric, f3, which turns in an elliptical pivoted yoke, f4, provided with, or made in, the upper part of a connecting-rod that con'-v nects at the lower end with a small crank, f5, of the valve f6, arranged in the V.lower end of the drill-teeth G, and which holds and retains the seedV until opened at regular intervals by the leccentricf. Wings H are attached to" the heels of the drill-teeth G, and have their upper ends lguided and braced in a brace, g, secured to the frame D. About midway of frame D a shaft, I, is jourualed, having secured to it at each end an arm, K, provided at its outer end with a friction-roller',-k, which bears down upon and depresses the bar L, pivoted at Z, and running in guides Z1 Z1. TheseA arms are rotated with the shaft I, which is set in lnotionl by a spider, l2, secured to the shaft, and operated by the drivers .feet or hands. It is also set in motion by the following mechanism, viz: On one end of the shaftI 1s arranged a clutch, fi, which is operated by a forkedhand-lever, il, fulcrumedat 2, andV extending close to the drivers seat. One side of the clutch is connected with the sprocketwheel m, which is drivenpby chains m2 and sprocket-wheel m1, on the main shaft S. When the clutch is in gear the revolution of the shaft S sets in motion the arms K. As these arms revolve, they alternately raise and lower the bars L, the bar on one side rising as that on the other falls. As they rise and fall, they draw to Veach side alternately the chain Z3, which is connected at each end with one of these bars, and in the middle with the connecting-rod f2, passing over the small sheaves Z4. By this means the connecting-rod f2 is moved from side to side alternately, andthus through the crank f1 rotates the small roller f f, and eccentric j'3 and valvef. On the center of shaft I is a cam, M, which raises and drops the hinged lever c, which is provided at its lower end With a shovel orspade, e', which,

These rollers are ar- A ranged on a small shaft, which is journaled in being alternately lowered and raised for equal distances, marks the ends of rows of corn on points at which the corn is dropped. Upon the front and rear cross-pieces B', are arranged uprights a a, to which are attached longitudi-l nal bars h, and on these at the rear end the drivers seat N is secured, which may be moved forward or backward, as desired. Near the center of the bars h is a short upright, O,

causing the shaft to revolve with the wheels actuating the wheel m1, when the machine is moving forward, but releasing the shaft when backing. By connecting the dropping apparatus with the small wheel m1 the irregularity in intervals of dropping the corn, caused by the wheels* B passing over clods or other irregularities ofthe surface of the ground, is reduced to a minimum.

' The operation of the machine is as follows: The seed being placed in the hoppers and the machine started, the driving-wheels rotate the sprocket-wheel ml, which, by chain m2, turns the sprocket m and shaft I with its arms K, which alternately force down the pivoted bars L, and these, by the chains Z3, move from side to side the bar f2, which, by cranks on the small shaft, rotate the rollers ff, which drops the seed at regular intervals by the cavities, the beveled guards fT preventing any corn not in the cavities from being carried over and dropped. The guards are constructed with upper surface of each sloping toward the rollers to an edge, said edge forming an angle with the axis of the roller. By this means the corn is'ithrown upward upon the guards. The seed lratchet and pawls in the recessed hubs.

are then caught by the small valve f6 in the lower ends of the tubular seed-teeth G, and dropped as the said valve is opened by the eccentric f4, and are then covered by the bent hubs H. Any backlash is prevented by the The hoppers and auxiliary frame are raised and lowered by the lever P, and held by the ratchet-teeth a.

Having thus described my invention, what I claim as my invention, and desire to secure by Letters Patent, is-

1. The inclined and beveled guards f7, constructed as described, in combination with rollers f and hoppers F.

2. rlhe combination of the seed-hoppers F, rollers f, guards f7, cranks f l, and connecting rods f2, with chain Z3, pivoted bar L, arms K,

and shaft I, substantially as and for the purpose specified.

3. The combination of seed-hoppers F, and rollers f, and crank f1, with eccentric f 3, yoke f4, valvef, and tubular teeth Gr, constructed and operated substantially as shown and described.

4. The combination of the shaft I, clutch t', lever il, spider iz, with frame D.

5. The combination of frame A, shaft S, wheels B, sprocket-wheels m m1, chains m2, shaft I, and arms K, with the bars L, chain L3, hoppers F, and rollers f, all constructed and arranged for operation substantially as and for the purpose herein set forth.

6. The marker, consisting of hinged lever e, and spade el, combined with frame E, and cam M, and shaft I, substantially as and for the purpose set forth and described.

7. The combination of main frame A, hinged I at the main axle with auxiliary frame D, carrying hoppers F, shaft I, and cam M.

In testimony that I claim the foregoing as my own I have aiiixed my signature in presence of two witnesses.
